- A \(7.1\)
- B \(8.0\)
- C \(5.8\)
- D \(6.9\)
Answer & Solution
Correct Answer
(D) \(6.9\)
Step-by-step Solution
Detailed explanation
\(\because \mathrm{HCl}\) is a strong acid. The concentration of \(\mathrm{HCl}=10^{-8} \mathrm{M}\) \(\left[\mathrm{H}^{+}\right]=\left[\mathrm{H}^{+}\right]\)obtained from \(\mathrm{HCl}+\) obtained by \(\mathrm{H}_2 \mathrm{O}\) \(\because \mathrm{HCl}\) is strong acid.…
